More and more studies are demonstrating that populations of animals‐from herbivores to top
predators, vertebrates and invertebrates‐are limited by their food, and that the availability of …

Feral cats have been directly responsible for the extinction of numerous species on islands
worldwide, including endemic species of mammals, birds and reptiles. The diet of feral cats …

Introduction Food availability is an important environmental cue for animals for deciding how
much to invest in reproduction, and it ultimately affects population size. The importance of …

Discerning the relative roles of adaptive and nonadaptive processes in generating
differences among populations and species, as well as how these processes interact, is a …

Although the lethal consequences of extreme heat are increasingly reported in the literature,
the fitness costs of exposure to sublethal high air temperatures, typically identified in the 30 …

Migration promotes utilization of seasonal resources, and the distance flown is associated
with specific morphologies, yet these relationships can be confounded by environmental …

Global declines in bird and arthropod abundance highlights the importance of
understanding the role of food limitation and arthropod community composition for the …

To anticipate seasonal change, organisms schedule their annual activities by using
calendrical cues like photoperiod. The use of cues must be fitted to local conditions because …

The duration of embryonic development (eg, egg incubation period) is a critical life-history
variable because it affects both the amount of time that an embryo is exposed to conditions …

Animal reproductive cycles are commonly triggered by environmental cues of favourable
breeding conditions. In arid environments, rainfall may be the most conspicuous cue, but the …
